We are currently running CUCM System version: 8.6.2.21900-5. We are having issues setting up and getting IP phones to connect from some employee homes. We have the licensing, and I know the setup works as I have been able to successfully confingure & connect several phones to our PBX from my home network.
What I cannot seem to find is a list of routers that are or are not compatible with the IP phone/vpn. I also need to find "checklist" of what to look for or what should be set up on a home network to make this setup for the users and IT staff easier.
I should note, that these users report that they can connect to our vpn fine via Anyconnect and their computers. 1 user even had access to other routers and on the 3rd router was able to get a connection and place a call.
I am in the process of getting the home router/modem make and models from these users if it helps.
